A fresh coat of paint makes everything it touches seem brand new. But such new beginnings cost real money. Professional painters charge around $4,000 for labor and materials to paint the exterior of a 2,500-square-foot, two-story home and roughly $5,500 for the interior. Painters’ rates may range from $20 to $60 an hour, but around $40 is typical in urban areas.
You are right on with this - why do people leave switch plates on when it's just so easy to take them off? Another thing that happened to us - we had the popcorn ceiling taken off and the ceiling painted white. When the job was done and I later went to change out all the fixtures/fans, they had left every fixture in place, so there was a large patch of popcorn and unpainted ceiling left behind - it just didn't dawn on me to specify that they take those down before scraping and painting. It was kind of a mess.
